HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 457, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 457, 727 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 818, 457, 727 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 818, 457, 727 is 1.

HCF(818, 457, 727) = 1

Highest common factor (HCF) of 818, 457, 727 is 1.

Highest Common Factor of 818,457,727 using Euclid's algorithm

Highest Common Factor of 818,457,727 is 1

Step 1: Since 818 > 457, we apply the division lemma to 818 and 457, to get

818 = 457 x 1 + 361

Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 361 and 457, to get

457 = 361 x 1 + 96

Step 3: We consider the new divisor 361 and the new remainder 96, and apply the division lemma to get

361 = 96 x 3 + 73

We consider the new divisor 96 and the new remainder 73,and apply the division lemma to get

96 = 73 x 1 + 23

We consider the new divisor 73 and the new remainder 23,and apply the division lemma to get

73 = 23 x 3 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 818 and 457 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(73,23) = HCF(96,73) = HCF(361,96) = HCF(457,361) = HCF(818,457) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 727 > 1, we apply the division lemma to 727 and 1, to get

727 = 1 x 727 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 727 is 1

Notice that 1 = HCF(727,1) .
